A person has to eat how many kg per day depends on the man or woman and their age. A person food also depends from he takes it from home or else outside. A person has to… eat 3,600 calories per person per day.Some calories content food like milk, meat, eggs, grain product, fruits and vegetables has a high content of calories that makes the person healthier.

This all depends on location, time of year, pasture quality and the breed of dairy cattle in question. The related question below asks the same question in a more general sens…e, and thus would answer this same question in a similar matter.

One 1000 lb cow with or without a calf will consume 25 lbs of feed/forage per day in dry matter (DM) ration. This is equivalent to what's called the Animal Unit (AU), since 1 …AU = 1 x 1000 lb cow with or without a calf. In context, this means that a cow or a bovine of any size will eat 2.5% of his/her body weight in DM ration per day. Actual or as-fed consumption varies with moisture content of the feed or forage.

This is one question that is impossible to answer because of many reasons such as: A cow cannot live on one type of forage for an entire yearA dairy cow will need to be treat…ed or given a preventative for bloat from a diet of nothing but alfalfa, if that is what the purpose of the question is.Location was never specifiedPrecipitation for the particular area was never identifiedA question of whether that cow is being grazed on alfalfa or if it's being fed all year round needs to be answeredWhat is the weight of this cow? What breed? If the cow is being fed, how many times during a growing year is that to-be-specified acreage of alfalfa should be cut? Once? Twice? Thrice?If the cow is not being fed a diet of strictly alfalfa as was posed in the second bullet, then what else is this cow being fed? As such, depending on your location and, as mentioned before, how many cuts of alfalfa are taken off if the cow is being fed and not grazed, acreage can range from 2 acres to 20 acres. If grazed, it would be significantly more than that.
